PATENT Orrin- FRANZ X. \VAGNER, OF NEW YORK, N. Y., ASSIGNOR TOUNDERWOOE TYPEVVRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEWJERSEY.

SPECIFICATION forming part of Letters Patent No. 763,083, dated June.21, 1904.

Original application filed July 5, 1902, Serial No. 114,362. Divided andthis application filed June 12, 1903. Serial No. 161,185, (No model.)

To aZZ whom it may concern.

Be it known that I, FRANZ X. W'AGNER, a citizen of the United States,residing in the borough of Bronx, city, county, and State of New York,have invented certain new and use ful Improvements in Type-Bar Mechanismfor Type-VVriters, of which the following is a specification.

My invention relates to type-bar mechanism for type-writers, and has forits object to provide a simple and efiective type-key for performingseveral functions and also to provide a shield for the said type-barmechanism to shield the eyes of the operator from observing the constantmotion of the type-levers.

I desire it to be understood that while I have shown what I consider atthe present the most effective way of carrying out my invention variousmodifications may be made without departing from the nature of myinvention.

This application is a division of one filed by me in the United StatesPatent Oflice July 5, 1902, Serial No. 114,362.

Reference is to be had to the accompanying drawings, of which Figure lis a central sectional elevation of a type-writer provided with myimprovements. Fig. 2 is a plan view of a portion of the same. Fig. 3 isa side view of one of my improved double-function keys; Fig. 4 is asectional plan thereof on line 4 4 of Fig. 3. Fig. 5 shows how one ofthe double-function keys may be converted into an ordinarysingle-function key. Fig. 6 is a sectional plan of the same on line 6 6of Fig. 5. Fig. 7 is a detail illustrating the connection of thetypelever with a link and elbow-lever, throughthe medium of which it isoperated from the keylever. Fig. 8 is a plan view of the same parts.Fig. 9 is a detail of the latch which is used to lock the end of theshield which is opposite to the hinged end. Fig. 10 is a View similar toFig. 3, but showing the parts in a different position. Fig. 11 is a sideview of one of my improved double-function keys looking from the otherside. Fig. 12 is an isolated viewof the key. Fig. 13 is an isolated viewof. the key-lever. Fig. 14 is an isolated view of the front key-section.Fig. 15 is an isolated view of the single-function key, and Fig. 16 is asectional view taken on line 16 16 of Fig. 11 with the key removed andlooking serves to act as a bearing to permit the carriage being moved tothe right or left on the track or rod D. ,E is a similar roller at thefront of the carriage and acts in a similar way for a similar purpose inconjunction with the track F. The roller E is shown mounted on thatportion of the machine which is ordinarilyused to shift the carriageintothe upper printing position. i

15 represents the type-levers, carrying the type 16 and fulcrumed at 17upon brackets 18, which are attached to the segment 19, forming part ofor secured to the frame 20 of the machine. Each of the type-levers 15 isconnected pivotally, as indicated at 21, with the link 22, the rear endof which is provided with a pin 23, having flat surfaces, as shown inFig. 7, and this pin is adapted to pass through a slot 24 intoa recessor socket 24 at the upper end of an elbow-lever 24, fulcrumed upon themachine at 25. The link 22 consists of two members which receive betweenthem the upper end of' the elbow-lever 24 and of the type-lever 15, andthese-members are made of elastic material, so thattheir forward endsmay be sprung over the pin 21, which connects them with type-levers 15.Thus the forward ends of links 22 may be readily detached when desiredfrom the corresponding type-levers, and by then turning the links upwarduntil the flat faces of the pin 23 stand vertical each link may bereadily removed from the upper end of the corresponding elbow-lever 24.The lower member of the elbow-lever 24 extends forward and is slotted toreceive a pin 25 upon the rear upon a rod or pivot 27, arranged to fitinto a finger. The shank 41 is further guided by recess 26.

by a spring 28, one end of which engages a l projection 28" in thekey-lever, while its other spring 44, which 18 secured to the member 39end abuts against an adjustable screw 29, supported on the frame of themachine. This construction allows the action of each key to be regulatedindependently.

When the keys are to perform their ordinary function only, they may beconstructed as shown in Figs. 5, 6, and 15. front portion of the keylever comprises a key 30, having a shank 31 and a longitudinal member32, provided with a lip 33, which extends into a recess at the front end26 of the member 26 of the key-lever. ther provided an arm 34, whichextends through an opening 26 to engage the arm 26 on the sideoppositeto that on which the member 32 is located. The front member ofthe key-lever is further held in position by means of a spring-latch 35,which is secured to the member 26, as shown at 36, and is provided atits front end with a pin 37, arranged to pass through a suitableaperture in the members 26 and 32. A projection 38 is provided,

so that the latch 35 may be readily manipulated. It will be understoodthat by swinging the latch 35 outward, so as to release the member 32from the pin 37, the forward member of the key is made free, so that itmay be first moved forward to disengage the lip 33 from the frontportion26" and then upward to entirely separate the parts 30, 31, 32, 33, and34 from the machine. WVhen these parts, which I may call a removablefront section of the keylever, have been taken off, Imay substitute forthem another front section which enables the key-lever to be used forperforming some function in addition to its ordinary function ofswinging the type-lever into the printing position. This double-functionattachment is shown in detail in Figs. 3, 4, 10,11, 12, 13, and 14 andcomprises a longitudinal sliding member 39, provided with a slot 39,which receives the pin 37. The spring 40 normally holds the member 39and the parts connected therewith in a forward position, said springbeing de tachably engaged with a lug 26 upon the keylever member 26. Atits front end the longitudinal member 39 is provided withlaterallyprojeeted flanges 39", provided with lips 39, projecting towardeach other, as shown in Fig. 4. At its rear end the member 39 has lips39 embracing the edges of the member 26, while lugs 41 serve the samepurpose at the front end of the member 39. (See Figs. 4, 11, and 16.) Itwill thus be seen that the front keysection 39 is movable longitudinallyof the rear section 26. Between the flanges 39 and the lips 39 is heldto slide vertically the shank 41 of the key 42, the latter beingprovided with an upward projection 43 for the purpose of enabling thefront key-section 39 to be readily pressedrearward by the operators Herethe There is fur- The key-lever is pressed forward a T-shaped projection39 (see Fig. 4) on the side of the member 39 near its lower end. A

and bears against a projection 41 of the shank 41, normally keeps thekey 42 in its upper position. A downward movement of the key 42 and ofthe shank 41 relatively to the key-lever 26 is normally prevented byprojection 41", which projects above a lug 26". It will be understoodthat the parts which I have termed the. double function attachment" maybe readily disconnected from the key-lemechanism ver 26 when desired, asbest shown in Figs.

12, 13, and 14. hen the key 42 is pressed down while in the positionillustrated by Fig. 1, it operates the corresponding type-lever 15 andalso, by means of an arm 26, acts on the universal bar 45, which movesfrom front to I the projection 43, and the member 39, slidinglongitudinally of and upon the member 26 thus disengaging the projection41 from the lug 26" and permitting the key 42 to be then presseddownward independently to perform a second function,as shown in Fig. 10.As an in--- stance of such second function I have shown a tabulatingdevice comprising a stop 49, pivotally connected at 49 to an arm 50,pivoted at 51, said arm 50 being provided with a forwardly-projectingmember 52, carrying a heel 52 which is adapted to be engaged by the toe41 of the key 42when-said key 42 isin its rear: Ward position for theperformance of its second function. Upon the rod 51 is also looselymounted the arm 52, carrying the heel 52, which is adapted to be engagedby the toe 41" of the key 42 when said key is in the position abovementioned. The length of the toe 41, which presses downward against theheel 52 when in operation, is such that the tabulating; stop 49 isbrought into operative position a fraction sooner than the toe 41, whichis a trifle shorter, pressing against the heel 52, carried by the arm52, releases the escapement mechanism from the rack, thus assuring thepositive action of the stop 49 against the stop 49" to arrest thecarriage. The connection of the escapement-release mechanism with thearm 52 may be accomplished in the usual way. It will be understood thatthis is only an instance, and the second function of the key may consistin the operation of any other The rearward movement of the member 39 andthe key 42 is limited by the slot 39 and the pin 37, while the shank 41is guided vertically by the lips 39 and the T- shaped projection 39".After pressure is removed fromthe key 42 the spring 44 serves to returnthe said key 42, with its shank 41, back to its original positionvertically, after which the spring 40 tends to bring the member 39 newagain in engagement with the key 4-2 and its shank 41 forward into thelocked position first mentioned, the entire key-lever, with all itsparts, being returned to the normal position by the spring 28 bearingagainst ably hinged at one side, as indicated at 47, so,

that it may be swung up to give access to the type-bars and othermechanism which it normally covers. 48 indicates a spring-latch forholding that end of the shield which isopposite to the hinge and is bestillustrated by Fig. 9. This shield has for its main purpose to concealthe type-bars, so that the eye of the operator may not be worried byconstantly observing the motions of the said type-bars.

IV hat I claim, and desire to secure by- Letters Patent, is

1. In a type-writer or like machine, a keylever having a latch and anattaching-surface in front of saidlatch in combination with akey-carrying section engaging said latch and said attaching-surface.

2. In a type-writer or like machine, a key lever having a latch and anotch in front of said key-lever in combination with a key-carryingsection engaging said latch and provided with a projection extendinginto said notch.

33. In a type-writer or like machine, a keylever having a latchand'attaching elements both in advance of and in the rear of the latchin combination with a key-carrying section engaging said latch andattaching elements.

4. In a type-writer or like machine, the combination of the key-lever, amember mounted to slide thereon lengthwise, a key member mounted toslide on said sliding member transversely and means for preventing amovement of the key member relatively to the sliding member when thesaid sliding member is in one of its positions.

5. In a typewriter or like machine, the combination of the key-lever, amember mounted to slide thereon lengthwise, and a key member mounted toslide on said sliding member transversely.

6. In a type-writer or like machine, the combination of the key-lever, amember mounted to slide lengthwise thereon, a key member mounted toslide transversely on said sliding member, said key member being capableof an independent movement relatively to the sliding member when saidsliding member is in one of its positions and means for returning thekey'member to its normal position.

7. In a type-writer or like machine, the combination of the key-lever, amember mounted to slide thereon lengthwise, a key member mounted toslide transversely on said sliding member and means for returning thesliding member and the key member to their normal positions.

8. In a type-writing machine or the like, the combination with theframe, the type-levers and mechanism for operating the type-levers, of ashield arranged in front of and above the path of the type-levers so asto conceal them in their movement, said shield being hinged at one endand a latch for locking the opposite end of said shield.
